. Specification of Letters Patent. Patented ltiity 31,1921.

Application filed April 15, 1919. Serial No. 290,137.

To all whom it mag concern.-

Be it known that we, BERT R, EMRIOK,

- and JOHN K. PoR'rER, citizens of the United States of America, both residing at Chauk, Upper Burma, India, havlng invented new and useful Improvements in or connected Deep well pumping apparatus as now usually constructed comprises a worklng,

barrel which is lowered into the bore hole or well, upon a string of pipe, known as tubing, an upright ball check or suction valve being arranged in the bottom of the said working barrel and having below it as much gas anchor, perforated pipe and ordinary anchor as is needed at each particular well or location, the whole being suspended in the bore hole.

Within this tubing is installed a string of wooden or iron sucker rods carrying on the lower end the working or delivery valve (also of the upright ball type) and cups, or a plunger, to make a fluid-tight fit 1n the working barrel. These sucker rods are reciprocated by a suitable mechanism to operate the plunger and the liquid is delivered through the tubing and around the sucker rods.

According to this invention a simpler and more efiicient apparatus is provided by dispensing with the sucker rods and utilizing the tubing for operating the pump and for the delivery of the liquid. For this purpose the plunger with the suction valve upon it is attached to the anchor pipe which rests on the bottom of the bore hole while the barrel which has the delivery valve at its upper end is attached to the tubing and is reciprocated thereby the delivery taking place through the tubing as above stated.

In the accompanying drawing Figure 1 is a sectional view showing our improved pump in position in a well, and

Fig. 2 is a sectional elevation of the lower part of the pump drawn to a larger scale than Fig. 1.

a indlcates the usual casing or lining of the bore hole which at its upper end is supported by the head 6 provided with a stuffing box, and 0 indicates the tubing which according to our invention serves for operating the pump and for the delivery of the oil or water the said tubing passing through thestufling box and being provided above the latter with the branch d through which the oil or water is discharged to the line.

0 indicates the reciprocating pump barrel which .is attached to the tubing 0 by a coupling 7 the said coupling also having affixed to it the cage 9 containing the delivery valve g? which,.as shown, is of the ball type.

The tubing 0 is of smaller diameter than the barrel 6 instead of being somewhat larger than the said barrel as was heretofore usual.

it indicates the pump plunger which is 7 the head 1 and at its lower end is secured to the head of the anchor tube m, which, according to our invention, rests upon the bottom of the well, the said anchor tube be ing perforated as usual and. having suspended. within itand attached to plunger h the pipe n for checking the entrance'of gas into the said plunger.

0 is a collar upon the plunger which cooperates with the head Z of the barrel in such a manner that it prevents the barrel and plunger from separating when they are lowered into or drawn from the bore hole, thereby obviating the necessity for drawing the plunger and barrel separately as is necessary when the ordinary tubing and sucker rods are used. 7

p is a spring which is arranged between the barrel'e and the anchor tube m to act as a buffer to prevent damage to the pump or the bending or buckling of the tubing 0,

should the latter part in working.

9, q are guide blocks applied to the tubing c to support the latter laterally and prevent vibration, the diameter of the said blocks being determined by the diameter of the bore hole or well casing a.

In the operation of the apparatus the tubing 0 is raised whereby the barrel 6 is also raised relatively to the plunger 7:, and

the said barrel is filled through the suction valve is. On the downward stroke of the barrel the oil or water contained therein is forced past the delivery valve 9 into the tubing 0, this movement being mainly effected by the weight of the barrel and the tubing.

For operating the pump We advantageously make use of mechanism of the kind shown in Fig. 1. This mechanism comprises an oscillating beam 7* mounted upon a pivot 01- fulcrum (not shown) and designed to be operated by hand or power, this beam being connected by a rod or pitman s to a lever t from which the tubing 0 is slung by a link a, the said lever being pivoted to a rocking support o. This arrangement allows of a Vertical pull being applied to the tubing 0. 7

Claim:

A. deep Well pump comprising a bore hole lining, a head and stuffing box .at the top of said lining, a delivery tube passing through said stufiing box, a reciprocating pump barrel attached to said tubing by a coupling 1,3e0,0ee

and provided With a head, a delivery valve and cage fixed to said coupling, a tubular pump plunger provided With a collar which cooperates with said head, said plunger being arranged in said barrel and passing through said head and having a case and suction valve fixed to its upper end, its lower end being secured to the head of a perforated anchor tube, springs arranged between said anchor tube and barrel, a gas checking pipe suspended in said anchor tube and extending below the perforations in the same, and guide blocks arranged on the tubing to prevent vibration.
